The blinking red LOS light on your PLDT router is always accompanied with no internet connection. Knowing how important the internet has become today and that most people are practically handicapped when there is no internet, it is good to know a thing or two about fixing the issue immediately.
This article will explain what is the meaning of the PLDT router LOS light blinking red, what are the possible causes as well as what you can do to fix it before you get in touch with the tech support.
Why Is My PLDT Router LOS Blinking Red Light?
LOS stands for Loss Of Signal, and as the name suggests, this light will start blinking or be solid red when a loss of signal occurs.
There are several different reasons why you are seeing the PLDT router LOS light blinking red.
- Damaged fiber cable.
- Loose connector.
- Service outage in your area.
The good thing though is that the solutions for this issue are pretty easy to implement if the problem is on your side. However, if your ISP is experiencing some problems or maintaining its network, you can’t do anything else but wait for them to get it fixed.
PLDT Router LOS Blinking Red – Quick Fixes
The following quick fixes are the most frequently used solutions when it comes to the PLDT router LOS blinking red. You don’t need to have any prior knowledge to implement them, except for the part where you need to replace the optical fiber cable. If you aren’t too confident in doing that, you can always leave it to the professionals.
And now, let’s see how to fix this issue.
Check The Fiber Optic Cable
The first thing to do in this case would be to check:
- whether the fiber optic cable is properly connected to the modem.
- whether it is damaged or bent abnormally.
- whether there are loose or damaged connectors.
Always check each end of the cable and if necessary purchase a new fiber optic cable.
If the LOS light is still blinking red after this inspection, and the eventual cable replacement or re-connection, try the next solution.
Reboot The Router
This is often one of the most recommended quick fixes because it is highly effective and easy to implement. Most networking problems can be fixed with it so make sure to remember to do it whenever you experience some problems with your home network.
To reboot your router, disconnect the power cord from the electrical outlet and wait for 5 minutes. After that, connect it back to the electrical outlet and wait for it to boot up completely. Check the LOS light now. It is very possible that it will be off now. However, if you still see the red blinking light try the next solution.

Check Whether Outage Is Causing The Problem
Sometimes your ISP will perform an unannounced maintenance or experience some power or service issues which will result in loss of signal.
The best way to confirm that this is causing the LOS light to blink red on your PLDT router is to contact support. If they confirm that an outage is the reason for the red LOS light blinking, then all you need to do and actually, the only thing you can do, is to wait till they get it fixed.
Another way to confirm an outage is by using websites like Outage.report and see whether PLDT is having an outage at the moment.
On the other hand, if they confirm that everything is fine on their end, ask them to check your line, restart your connection or guide you through some basic troubleshooting steps. If they can’t help you remotely, they can always send a technician to check the problem on site as well as check the PLDT router itself.
We hope that you have managed to fix the PLDT router LOS blinking red before having to get in touch with the PLDT support. Generally, this network problem is closely connected to the optical fiber cable. If it has been damaged or extremely bent, or maybe the main line was cut off accidentally, you will see the LOS light blinking red. The same will happen if your ISP experiences service outage for some reason.
So, if you check the cables and reboot the router, and the red light is still blinking, it is very possible that the reason is on the ISP’s side. If that is the case, contact the support and ask for assistance. We are pretty sure you will get the problem fixed in no time.

Please check our connection.
Please restore our connection immediately. We surprised of the disconnection despite we are updated of our monthly subscription payment. We don’t received any advisory and technical notification from the service provider. Thus, the subscriber request for the prompt restoration of the connection including the telephone line.
Hello PLDT FiberHome
Thru the service provider or contractor. We enjoyed your services even after the onslaught of Super Typhoon however we surprised the abrupt disconnection. Despite we made update on the monthly subscription payment. Base on the foregoing, I lodged a complaint letter to the technical service provider, PLDT including NTC relative to the abrupt disconnection of my subscription with FiberHome 2,999 plan or unlimited 100mbps equivalent. We wish that this will restore on the earliest possible time. Thank you.
